Error with ?? in Typesense.php

[manavo]

Description

Because of how the ?? check works, it will never actually try and load the document/collection in these places:

https://github.com/typesense/laravel-scout-typesense-driver/blob/master/src/Typesense.php#L89
https://github.com/typesense/laravel-scout-typesense-driver/blob/master/src/Typesense.php#L118
https://github.com/typesense/laravel-scout-typesense-driver/blob/master/src/Typesense.php#L163

The typesense library will always return the object, so the check for existence and then the null fallback are pointless, and actually breaks it.

I'll submit a PR for this tomorrow, unless someone beats me to it (@hi019?)

It was introduced in the last commit on the old repo by @AbdullahFaqeir: devloopsnet/laravel-scout-typesense-engine@55efffa, but won't work in this case and needs to be removed.
